CLOTHES-WRINGER.

SPECIFICATION forming part of Letters Patent No. 447,609, dated March 3, 1891.

Application filed December 9, 1890. Serial No. 374|Ol'7. (No model.)

To all whom it may concern:

Be it known that I, LOUIS T. GORENFLO, a citizen of the United States, residing at Erie, in the county of Erie and State of Pennsylvania, have invented certain new and useful Improvements in Clothes-ll'vringers; and I do hereby declare the following to b'e a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appert-ains to make and use the same.

This invention relates to clothes-Wringers; and it consists in certain improvements in the construction thereof, as will be hereinafter fully set forth, and pointed out in the claims.

The purpose of the invention is to adapt roller-bearings to the shafts of clothes-wringers, whereby the operation of the machine will be made easy.

The invention is illustrated in the accompanying drawings, as follows:

Figure 1 shows a fragment of a clotheswringer frame-work, rolls, rbc., in vertical section. along the axis of the rolls, the same having my improvement incorporated therein. Fig. 2 shows one of the uprights of the frame-work in vertical section on a line transverse the axis of the rolls. Fig. 3 is a cross-section of the upright post shown in Fig. 2 on the line oc in said Fig. 2. Fig. 4 is a like section to Fig. 3 on a larger scale and with the shaft and shaft-bearing of one of the rolls shown in place. Fig. 5 is a side elevation of one of the upper shaft-bearing boxes. Fig. 6 is a like view to Fig 5, but shows a lower shaft-bearing box and has the keeper-ring h removed.

A marks the upright posts of the frame,- work; B, the upper cross-piece; C, ythe pressure-bar; D, the tension-screws; E, the pressure-springs; F F, therolls; F F', the shafts; ff, the gears; I-I H', the bearing-boxes; I I, the anti-friction rolls of said bearings, and 71. the keeper-rings which keep the rolls I in the boxes H H.

The parts of the machine, with the exception of the bearing-boxes H H and their contained parts and a slight modification of the form of the frame-posts incident to the use of said boxes, may be of any of the various constructions commonly used. The vertical slots in the posts A are channeled out on their inner walls, so as to form the lips or flanges a a, which abut against the sides of the bearing-boxes, as seen in Fig. 4. The bearing-boxes H H are alike for both the upper and lower shafts, except that the lower box II is preferably made seniicircular on its lower side to conform with the form given to the bottom of the slot in the postA by the shaping-machine generally used for forming that slot. These boxes are blocks of metal with a transverse opening which isledged at h2, so as to receive the rollers I, which surround the shaft, and a second ledge or rabbet 7L to receive the keeper-ring 7L, which retains the rollers I within the box, and when the boxes are placed within the forks of the posts A the lips a retain the parts in place and form guides for the upper boxes, which move up and down with the upper roll.

I am aware that roller-bearings for shafts are common in machinery, and I make no claim to the use of the same in any broad sense; but in the application of such bearings to clothes-Wringin g machines special features of construction are required, and it is therein that the novelty of my device resides.

That I claim as new is- 1. In a clothes-wringing machine, the combination, with the roll-shafts F', of the surrounding bearing-boxes, the rollers I within said boxes around said shafts, the keeperrings h, retaining said rollers Within said boxes, and the forked posts A, having inwardly-extending lips a, which flank the sides
